Yamagata Kaminoyama City
An inn of seasonal gardens and natural onsen water fed straight from the source, facing the Zao mountain range
Mikiya Sansorai is an onsen ryokan in Kaminoyama, Yamagata Prefecture. Surrounded by peaceful farmland, the inn is built entirely on a single story, and from inside you look out on a Japanese garden that changes with each season. Its pride is the water of Kaminoyama Onsen, rich in metasilicic acid and known as a “bath of beauty.” In the main bathhouse with its fine views and in the open-air bath that takes in the whole Zao mountain range, you can soak to your heart’s content in natural onsen water as soft as skin lotion, fed straight from the source, never recirculated. There are also rooms with their own open-air bath, where you have the source water all to yourself, and rooms with an indoor bath. Over kaiseki that brings Yamagata’s nature and the bounty of the countryside to the table, you can spend calm hours far from the bustle of the city.

A main bathhouse where you look out on the mountains from a spacious stone tub. Natural onsen water rich in metasilicic acid, as soft on the skin as lotion, flows in straight from the source, never recirculated. Well regarded as a “bath of beauty,” this fine water warms the body to the core and brings deep relaxation.

An expansive open-air bath with the Zao mountain range, the symbol of Yamagata, spread out directly in front of you. In some seasons you soak at leisure in natural onsen water fed straight from the source, never recirculated, while the wind carries the scent of ripening rice. The grand natural scenery and the pleasant feel of the water gently ease away the fatigue of everyday life.

Onsen baths of their own in some of the rooms. Hana and Inaho have an open-air bath fed straight from the source, never recirculated; Ren has an open-air bath of hinoki filled from the source; and Kiyose has an indoor bath where you have the source all to yourself. In a private space, you can enjoy the fine water of Kaminoyama Onsen whenever you like.
